Metal Melting Treatment

Removing Impurities

  It is very difficult for small inclusions in steel liquid to float, and only when they gather together does it become easier for them to float. Using ultrasonic metal melting equipment to introduce ultrasound into the solution, the standing wave of ultrasound can successfully stratify and concentrate the powdery inclusions in the solution.

Removing Gases

  When elastic vibrations of ultrasound are introduced into molten metal, cavitation occurs. The dissolved gases in liquid metal move towards the cavity, promoting the formation of a bubble core and continuously growing it until it reaches the size that can be discharged from the molten metal.

Grain Refinement

  During the continuous casting process of aluminum-silicon alloy, ultrasonic treatment can refine the grain of the cast billet, improving the alloy's plastic deformability for better application in building materials and automotive engine pistons. Applying ultrasound to aluminum alloy liquid can avoid the generation of oxide inclusions and refine its microstructure.

Improving Casting Quality 

  Acting on the crystallizer, it improves the surface quality of the cast billet. It can be used for small square billets, large square billets, and slab billets without negative sliding during ultrasonic vibration. After applying ultrasonic vibration to the crystallizer during the casting of small square billets and large square billets, a smooth surface of the cast billet is obtained.
